About this study

Official title: Short-term Efficacy of Interleukin-2 Gargle Combined With Systemic Use of Glucocorticoids in the Treatment of Oral Mucosal Lesion in Pemphigus Vulgaris: a Randomized, Controlled, Double-blind, Multicenter Clinical Study

This clinical study will test the short-term efficacy of interleukin-2 gargle combined with systemic use of glucocorticoids in the treatment of oral mucosal lesions in mucosal-dominant pemphigus vulgaris and moderate mucocutaneous pemphigus vulgaris.

Read the detailed description

Backgrounds: Pemphigus vulgaris (PV) is a life-threatening autoimmune bullous skin disease characterized by blisters or bullae on the skin and mucosal membranes. The formation of painful erosion surface after rupture of blisters may result in infection, haemorrhage and even electrolyte imbalance due to excessive water loss. PV can be divided into two types: mucocutaneous PV and mucosal-dominant PV. Patients with mucocutaneous PV not only suffer from severe mucosal damage but also general skin lesions, while slight or no skin lesions involved in patients with mucosal-dominant PV. Oral mucosal damage occurred 3 months to 1 year before skin lesions in about 60% of PV patients. The most common involving parts of the oral mucosa are pars buccalis and oropharynx, presenting with persistent and painful erosion or ulceration, which leads to difficulty in feeding and aggravates the electrolyte imbalance.

Glucocorticoid is the main treatment strategy of PV. Besides the blisters and erosion, complications of long-term use of glucocorticoid are also the death causes of PV patients, such as osteoporosis, hyperglycemia, hypertension, hypokalemia, femoral head necrosis, peptic ulcer, and infection. Many patients have gotten remission from the standard application of glucocorticoids, Immunosuppressants and biological agent. However, there is still a part of patients that are insensitive to these drugs or intolerant the side effects of corticosteroids. Even for those steroid-sensitive patients, the healing of oral mucosa often takes a long course, lasting from weeks to months, which has a serious impact on the quality of life. It is a critical problem to develop novel therapeutics to accelerate the healing of oral mucosa.

Recombinant human interleukin-2 (rhIL-2) is an immunomodulator agent commonly used in the treatment of patients with tumours. The safety and efficacy of low dose rhIL-2 have been demonstrated in the treatment of type I diabetes, systemic lupus erythematosus, and graft-versus-host disease. We found that topical application of rhIL-2 can effectively relieve pain and improve the condition of oral mucosa for PV patients. Studies have shown that IL-2 selectively modulates CD4+ T cell subsets and increases the amounts and function of regulatory T cells. Moreover, IL-2 plays an important role in the proliferation of fibroblasts and wound healing. These evidences provide us the theoretical basis to explore the potential mechanism of rhIL-2 in treatment of mucosal damage of patients with PV.

Design of Study: This is a randomized, controlled, double-blind, multicenter clinical trial to assess the safety and short-term efficacy of rhIL-2 for oral erosion in patients with pemphigus.

Methods: rhIL-2 oral gargle combined with the standard dose of glucocorticoids (mucosal-dominant PV: prednisone 0.5 mg/kg/d, mucocutaneous PV: prednisone 1 mg/kg/d) will be applied to pemphigus patients meeting the inclusion criteria. The end points include clinical response and immunological changes, as well as safety.
